El chatbot de IA ChatGPT imita a sus usuarios para parecer inteligente

LA JOLLA—The artificial intelligence (AI) language model ChatGPT has captured the world’s attention in recent months. This trained computer chatbot can generate text, answer questions, provide translations, and learn based on the user’s feedback. Large language models like ChatGPT may have many applications in science and business, but how much do these tools understand what we say to them and how do they decide what to say back?

Telomeres, mitochondria, and inflammation oh my! Three hallmarks of aging work together to prevent cancer

LA JOLLA—As we age, the end caps of our chromosomes, called telomeres, gradually shorten. Now, Salk scientists have discovered that when telomeres become very short, they communicate with mitochondria, the cell’s powerhouses. This communication triggers a complex set of signaling pathways and initiates an inflammatory response that destroys cells that could otherwise become cancerous.


El profesor John Reynolds, de Salk, nombrado miembro de la AAAS en 2022

LA JOLLA (January 31, 2023)— Salk Institute Professor Juan Reynolds has been named a 2022 Fellow of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society and publisher of the journal Ciencia. Reynolds is among 506 new AAAS Fellows spanning 24 scientific disciplines who were nominated by their peers for their distinguished efforts to advance science.


La suplementación con aminoácido serina alivia la neuropatía en ratones diabéticos

LA JOLLA—Approximately half of people with type 1 or type 2 diabetes experience peripheral neuropathy—weakness, numbness, and pain, primarily in the hands and feet. The condition occurs when high levels of sugar circulating in the blood damage peripheral nerves. Now, working with mice, Salk Institute researchers have identified another factor contributing to diabetes-associated peripheral neuropathy: altered amino acid metabolism.


Salk scientists receive $1.5 million from Sol Goldman Charitable Trust to research multiple sclerosis treatments

LA JOLLA—Profesor del Salk Ronald Evans and an interdisciplinary group of Institute researchers have been awarded a two-year, $1.5 million grant from the Sol Goldman Charitable Trust at the direction of cardiologist and Salk Trustee Benjamin Lewis. The award will fund a research project to explore connections between the gut, brain, and immune system in search of new therapies for patients with multiple sclerosis (MS).


La capacidad del cerebro para percibir el espacio se expande como el universo

LA JOLLA—Young children sometimes believe that the moon is following them, or that they can reach out and touch it. It appears to be much closer than is proportional to its true distance. As we move about our daily lives, we tend to think that we navigate space in a linear way. But Salk scientists have discovered that time spent exploring an environment causes neural representations to grow in surprising ways.


Time-restricted eating reshapes gene expression throughout the body

LA JOLLA—Numerous studies have shown health benefits of time-restricted eating including increase in life span in laboratory studies, making practices like intermittent fasting a hot topic in the wellness industry. However, exactly how it affects the body on the molecular level, and how those changes interact across multiple organ systems, has not been well understood. Now, Salk scientists show in mice how time-restricted eating influences gene expression across more than 22 regions of the body and brain. Gene expression is the process through which genes are activated and respond to their environment by creating proteins.


La microproteína aumenta el apetito en ratones

LA JOLLA—La obesidad y las enfermedades metabólicas, como la diabetes, son extremadamente comunes en Estados Unidos. Las diminutas proteínas llamadas microproteínas han sido pasadas por alto en la investigación durante mucho tiempo, pero nueva evidencia demuestra que tienen un papel importante en el metabolismo. Científicos del Salk descubrieron que tanto la grasa marrón como la blanca están llenas de miles de microproteínas previamente desconocidas, y demuestran que una de estas microproteínas, llamada Gm8773, puede aumentar el apetito en ratones.


Salk scientists develop compound that reverses gut inflammation in mice

LA JOLLA—A drug developed by Salk Institute researchers acts like a master reset switch in the intestines. The compound, called FexD, has previously been found to lower cholesterol, burn fat, and ward off colorectal cancer in mice. Now, the team reports in Actas de la Academia Nacional de Ciencias on December 12, 2022, that FexD can also prevent and reverse intestinal inflammation in mouse models of inflammatory bowel disease.


Activando el interruptor: científicos de Salk arrojan nueva luz sobre los cambios genéticos que “encienden” genes cancerosos

LA JOLLA—Cancer, caused by abnormal overgrowth of cells, is the second-leading cause of death in the world. Researchers from the Salk Institute have zeroed in on specific mechanisms that activate oncogenes, which are altered genes that can cause normal cells to become cancer cells.


Las neuronas deterioradas son la fuente de la inflamación cerebral humana en la enfermedad de Alzheimer

LA JOLLA—A pesar de décadas de investigación, la enfermedad de Alzheimer sigue siendo una demencia debilitante y, finalmente, mortal sin opciones de tratamiento efectivas. Más del 95 por ciento de los casos de enfermedad de Alzheimer no tienen un origen conocido. Ahora, científicos del Salk Institute han descubierto que las neuronas de personas con enfermedad de Alzheimer muestran deterioro y sufren un proceso de estrés en la vejez llamado senescencia. Estas neuronas presentan una pérdida de actividad funcional, metabolismo alterado e inflamación cerebral aumentada.

LA JOLLA—The Salk Institute has named Luzilda “Lucy” Arciniega director of Diversity Strategies & Implementation, as the Institute continues to expand its focus on efforts that support recruitment, retention, leadership, and cultural connectivity throughout its vibrant campus.


El crecimiento de neuronas motoras guiado por una “relación de amor y odio” con los vasos sanguíneos

LA JOLLA—When neurons involved in movement—called motor neurons—form, they must build connections that reach from the brain, brainstem, or spinal cord all the way to the head, arms, or the tips of the toes. How neurons navigate these systems and “decide” where and how to grow has largely been a mystery.


In Memoriam: Georg Heinrich “Heini” Thyssen-Bornemisza

LA JOLLA—The Salk Institute recently lost a dear friend and former Trustee when Georg Heinrich “Heini” Thyssen died on September 30, 2022.


Científicos de Salk descubren moléculas antiinflamatorias que disminuyen en el cerebro envejecido

LA JOLLA—Aging involves complicated plot twists and a large cast of characters: inflammation, stress, metabolism changes, and many others. Now, a team of Salk Institute and UC San Diego scientists reveal another factor implicated in the aging process—a class of lipids called SGDGs (3-sulfogalactosyl diacylglycerols) that decline in the brain with age and may have anti-inflammatory effects.
